Yes, you can select a set of rows that were / will be valid in a past / future time. This is called Time Travel in DB2, but you have to configure / create the table with the extra columns in order to activate this feature. This is new in DB2 10, but I think it is not available in all editions.
For more information, take a look at this: http://www.ibm.com/developerworks/data/library/techarticle/dm-1204db2temporaldata/
Remember, there are two concepts: business time and application time, and when using both is called bi-temporal.
